Be it known that l, Dario `fiunmanina, a citizen of the United States, and a resident of Syracuse, in the countyoi Unondaga and State. ot New York, have invented a certain new and useful Mining and Proportioning V.Device or Valve, of which the iollowing is a specification.

This invention has 'for its object a proportioning and mixing device or Valve, par-l ticularly applicable for proportioning and combining elements or streams to be mixed in definite ratios, which device or valve is particularly simple in construction and highly ellicient in use and lurther'which can be readily attached in a threaded pipe line.

This proportioning and n'iixing device or valve is designed primarily for automatically mixing and proportioning any two elements or substances or fluids, dry or Wet, such as air with gas, liquid or powdered 'tucl for heat, light, and power generation; or air with water, oil, etc. as in air litt pumps g or streams ot any material coinbined for any purpose in just the right ratio by forming suchr elements or substances or tluids in two concentric conical sheet streams otl any desired thicknesses which iinpinge upon and intermingle 'with each other in one stream so as to produce the highest etiiciency under all working conditions at 'full or at fractional capacity.

The invent-ion consists in the novel ifeatures and in the combinations and constructions hereinatter set forth and claimed.

ln describing this invention, reference is had to the accompanying drawingsY in which like characters designate corresponding parts in all thevieWs. Figs. l and 2L are respectively, an elevation, and a vertical sectional View of one 'torni oit' my mixing and proportioning Valve or device.

Fig. 3 is a sectional View on line 3-f3, l" l, 1 lf f-l, 5 and (i are views similar to l ot other 'Forms or embodiments of iny invention.

connected in series, in a pipe line, Fig. i being a. longitudinal sectional View, Fig. 8, an elevation, partly in section.

This proportioning and mixing valve [or device 'lor combining ystreams of materials or substances or fluids to be mixed in lined 'Tand 8 are forms ci my invention ratios compr concent l generally, inner and outer sages tor the materials or streams to be terinfingled Within the outer member,A the yinner `ine y oer `being formed with its passage .substantially coaxial with the outer ot discharge .slots near its inner end connecting its passage with the passage oi: 'the outer member. `Preferably, the outer member is formed with an intake opening or openings and a conical portion ooniining a contracting passage; and the inner member extends into the body portion of the "outer member and has a conical portion eX- rending into the contracting passage, the

slots of the inner member opening through the conical wall into the conical passage of ,thereofv to vary the effective cross sectiona area olf the concentric conical passao'e near the discharge slots at the inner end olf the inner member and also the cross cylindrical members formed with r and being also formed With ya series ot the outer member and adjustable sectional area ot the contracting passage or` the outer member, and thus maintain the 'Lio oi air or other gas to the -fuel in a io per unit of Volume.

s the outer member. 2 the inner member, the outer member including' a cylindrical body portion 3 and a contractingconical portion Ll which coniines a contracting passage. 5. 'The body portion 3 is lalso formed with an inlet or inlets 6 for the periphery oit the pipe i' into the concentric` conical passage between the closure or vion piece 8 a sleeve element 1l. sion piece 3 may be a plug tted into the slotted end of the pipe T or may be cast integral with the pipe or tube 7. closure'or extension piece 8 also er tends axially in the narrower portion of' the contracting passage 5 ot the outer member and is formed conical at i0. As shown in Figs. l and 2 the element ll is adjustable lengthwise oi" the pipe 7 and the outer member l and formed with an external conical tace l2 at its inner end opposed and substantially parallel to the adjacent inner wall ot the conical portion Llof the outer member l at the Larger end oi' the passage confined by saidwall, and also with an internal beveled or conical tace 13 opposed and substantially parallel to the adjacent beveled face le on the rear portion ot the extension piece 8 near the/slots 9. These two conical surfaces 13, M form the passages 9a. Upon ustn'ient oi the element or sleeve 11 axially in one direction or the other the size ot the concentric conical passages 9a to the common outlet 5 are proportionately adjusted and the ratio of the streams passing therethrough remains the same per unit volume.

As illustrated in Figs. i and 2 the sleeve member il is connecte( at l5 to the cylindrical body portion 3 ot the outer member l by screw threads, and for facilitating the adjustment ot said inembe.,l it is toured with a peripheral annular handle flange i6. The extent or' such an adjustment may be determined by an indicator piece l? secured in any suitable manner as by a screw 1 8 to the body 3 of the outer member l and overlyino` the periphery of the handle Yflange 16, this ange and the indicator being` provided with suitable micrometer graduations.

The tube or pipe i' is preferably held trom endwise movement by any suitable means a pin or bolt i8 extending,` diametrically through the conical portion l oit' the outer member i and through the extension piece i rllhe movement of the sleeve or plug element ll outwardly is limited by a stop pin l) on the tube the outer side or end ot the sleeve element ll. rllhe tube or pipe 7 e1;- tends beyond the end ot the sleeve element ll and is threaded at Q0 and the outer or lower end of the conical portion -l or' the outer member is lilrewisethreaded at 2l, both for connection in a pipe line by standard pipe connections.

Simple calculations prove that the various dimensions of the separate parts composing this mixing` proportioning` device can be mutually proportioned, so that the ratio between the passage areas for both streams their entrances into the conical passages ,ff remains practica-.ll the same ully opened am when at tl limit where they are nearly C.

bota when these passages are sed. Therefore choosing these dimens ns so to conform to the ratio `tound by preliminary en, eriments by means of the proportioning valve with a double sleeve as hereinafter described to give the martimum efficiency, this mixing and proportionelements 22, 23, the element 22 threading' into the body portion 3 ot' the outer member l and the inner sleeve element Q3 threading on the pipe i' and slidably fitting with.- in the bore of the sleeve element 22, thus by turningthe sleeve element 23the amount ot' material or substance passingthrough the 'slots 9 can be regulated, and by turning;`

the sleeve element 22 the amount of material passing' into the passage 5 from the inlet 6 can be adjusted.

As seen in Fig. 5 in cases where'the average rate of flow is about constant and no regulation is needed, then the mining` and proportioning` valve or device for permanent service may be made with the inner regulating member stationary.

,ln Fig. i' the inner sleeve element 24 thereof is permanently secured to the body portion 3 ol: the outer member l as by screws Q5, and it is permanently secured as by a set screw 26 to the pipe or tube 7, all three forming one compact stationary body.

Referring,F to Fig'. 6 in cases where one ot two streams to be combined consists ot heatved air, steam or any other substance other than tree atmospheric air, the upper or body part ot the outer member l is enclosed in the jacket 27 provided `with a suitable nipple tor attachment to av reed oi e. This 1 L 1 i L i jaciret may ne fitted onto the outer' member l. or formed integral therewith or the ooeninus .y i i L cas 6 may be omitted and the nipple 28 onto the upper bod ln cases where the ratio between the streams to be combined is exceptionally large or in cases where more than two streams of difterent substances are to be combined in fixed ratios, then two or more mixing; and proportioninr,- valves or devices may be connected in series in the pipe line shown in 7 and 8. Vilhen used -for two streams only, say air and fuel, the series or battery oil such devices as shown in Fig. 7 ,qives an ultimate ratio, air and fuel ot (ln the second mi and proportioning valve in the series 1n the direction ol the flow, Fig. 7, the inner pipe T, memk and sleeve 24;? are preferably Atasigened together or non-adjustable. that is, of the form shown in Fig. 5. lt tlis series or :atl-ery shown in Figs. T and 8 is used for combining three streams of different substances .iirfixed ratios, then the no vfree stream access froma surrounding mass as air, Water Aor oil, isto be provided with vthe enclosing jacket as shown in Fig. 46. In cases of heavy, non-volatile liquid fuels Where exceptionally large quantities of air are required several mixing and proportion,- ingvalves'i, B', C may bearranged in series in the pipe line as shown ii'iiliig. 8 Where the ultimate ratioobtained` between air and fuel is as high as 5000 :1.`

vlnthe arrangement shownin Fig. 8 the first of the valves in the series', that is, the

valve A nearest-the' fuel tank isy provided with' the inner member adjustable as in Fig. l and the two remaining mixing and proportioning valves are preferably of the form shown in Fig; 5. I

i In use, one or more ofthesemixingr valves can be readilyconnected inthe pipe line owing to theconcentric arrangement of vthe iiiiierand youter membersand to the threaded eiids()1 2l and the supply adjustment may be madefby adjustingthe inner sleeve inemberli, Fig. 9i or both sleeve members 22, 23 when the-form shown in Figs. 4 or Gare employed. i i f' in operation, the larger :one of thet'vvo streams to be mixed entersthe passages@ from the outer .air or `from the jacket 27 when any substance other than atmospheric air is used, and the other stream enters through the pipe 7, slotsf9 and passages 9 and mixes with the air inthe passage 5. In casey the tivo streams to be combinedare air andv 'Water ror air and oil, as in airdift pumps, then the air pressure pipe joins the inner pipe 7, While the 'Water or oil is `allowed to iioiv freely into the outer body l. This mixing and proportioning valve is particularly advantageous iii that it is simple-iii construction, readily attached in the pipeline,readilyadapted to the conditions and automatically `maintains all the time, a fixed ratio per unit of volume, ofthe elements of the resultant mixture, correspondingto the highest efficiency. y n
